Bowl of Heaven

When the SunSeeker leaves Earth, bound for the planet called "Glory," its crew knows they will never see the Earth again. None of them can ever have imagined, however, what they will find along the way. A gargantuan object, with its own star nestled inside. BOWL OF HEAVEN. The bowl-shaped structure is following the same path as the SunSeeker, and it has a habitable area the size of millions of Earths. A landing party is sent to the surface, where they encounter some of the structure's inhabitants - wildly differing species, and not all of them friendly.
